How Does Surrogacy Work?
For intended parents, the surrogacy journey can feel overwhelming at first. There are medical decisions, legal requirements, matching, financial planning and many smaller steps between the first consultation and welcoming a baby.
Understanding the process in advance can make the journey easier to navigate. In gestational surrogacy, an embryo created through IVF is transferred to a gestational surrogate, who carries the pregnancy for the intended parents. Because the surrogate's egg is not used, she is not genetically related to the baby.
1. Start With a Surrogacy Consultation
The first step is understanding whether surrogacy is the right family-building option for you. During an initial consultation, intended parents can discuss their medical history, family-building goals, timeline, potential treatment options and the practical aspects of the journey.
This is also the right time to understand which medical professionals, fertility specialists, legal professionals and support teams may be involved.
2. Create or Prepare the Embryos
Gestational surrogacy typically involves IVF. Depending on the circumstances, embryos may be created using the intended parents' eggs and sperm, donor eggs or donor sperm.
The fertility team will determine the appropriate treatment plan and prepare embryos for a future transfer.
3. Find and Match With a Gestational Surrogate
Matching is one of the most important stages of the surrogacy journey. Intended parents and potential surrogates need to understand each other's expectations, communication preferences and plans for the pregnancy.
A carefully structured matching process can help both parties enter the journey with a clear understanding of their responsibilities and expectations.
4. Complete Medical and Psychological Screening
Before an embryo transfer takes place, the gestational surrogate undergoes medical evaluation and screening. Depending on the program and medical team, additional psychological and background assessments may also be part of the process.
The purpose of screening is to make sure the surrogate is medically and emotionally prepared for the pregnancy and that the appropriate support systems are in place.
5. Complete the Legal Process
Surrogacy also involves important legal considerations. The intended parents and surrogate generally work with qualified legal professionals to establish the terms of their agreement before the pregnancy proceeds.
Because surrogacy laws vary significantly between jurisdictions, intended parents should obtain independent legal advice relevant to their specific circumstances.
6. Prepare for Embryo Transfer
Once the medical and legal requirements have been completed, the surrogate's treatment cycle can begin. Medication may be used to prepare the uterine lining for embryo transfer according to the fertility specialist's protocol.
The fertility team then schedules the embryo transfer based on the medical plan.
7. Embryo Transfer and Pregnancy
During embryo transfer, the selected embryo is transferred into the surrogate's uterus. A pregnancy test is performed after the appropriate waiting period.
If pregnancy is confirmed, the surrogate continues receiving appropriate medical care and monitoring throughout the pregnancy.
8. Pregnancy and Ongoing Support
Pregnancy is an important part of the journey for everyone involved. Regular prenatal care helps monitor the health of the surrogate and developing baby.
Clear communication between intended parents, the surrogate and the professional team can also help everyone navigate appointments, milestones and important decisions throughout the pregnancy.
9. Birth and Becoming Parents
The final stage is the birth of the baby. The medical and legal teams help coordinate the arrangements surrounding delivery and parentage according to the applicable laws and agreements.
For intended parents, this is the moment when months of planning, medical treatment and preparation become the beginning of life as a family.
How Long Does the Surrogacy Process Take?
There is no single timeline that applies to every surrogacy journey. The overall duration can depend on factors such as embryo availability, medical screening, matching, legal requirements, fertility treatment and the pregnancy itself.
For this reason, intended parents should plan for a process that may take considerable time rather than expecting a fixed schedule.
What Does Surrogacy Cost?
The total cost of surrogacy can include medical treatment, IVF, surrogate-related expenses, legal services, professional support and other journey-specific costs.
Costs vary substantially depending on the country, medical requirements and the type of surrogacy program selected.
